You’re standing in San Diego, clutching a passport and a boarding pass, looking at a purple bridge that technically spans two different countries. It’s weird. It’s also the smartest way to get to Mexico City from Tijuana if you’re living anywhere in Southern California. Honestly, driving across the Otay Mesa border or waiting in that soul-crushing San Ysidro line just to catch a domestic flight feels like a rookie mistake once you’ve done the Cross Border Xpress (CBX) walk.
Mexico City—or CDMX, as everyone calls it now—is huge. Massive. It's a high-altitude sprawl of ancient Aztec foundations and neon-lit taco stands. But getting there from the north shouldn't be an ordeal.
Most people think they have to fly out of LAX or San Diego International. They don't. Those flights are "international," which means you’re paying international taxes, dealing with TSA, and likely paying $400 to $600 for a round trip. Flying out of Tijuana is a domestic flight. It’s basically like flying from Chicago to New York, but with better snacks and a lot more Spanish.
The CBX Reality Check
The Cross Border Xpress is a pedestrian bridge. It connects a terminal in San Diego directly to the Tijuana International Airport (TIJ). You park your car in a dusty lot in the U.S., walk across a bridge, and boom—you’re at your gate in Mexico. No traffic. No border patrol agent leaning into your car window asking if you have any oranges.
But here’s the thing: you can’t just walk across it because you feel like it. You need a boarding pass for a flight leaving TIJ within 24 hours. You also need a CBX ticket. Prices fluctuate, but expect to pay around $20 to $30 each way. Pro tip? Buy the round-trip ticket online before you get there. It saves you five bucks and the headache of fumbling with a kiosk while a line of impatient travelers breathes down your neck.
What actually happens when you cross
You walk through a duty-free shop—because of course you do—and then you hit Mexican Immigration. If you aren't a Mexican citizen, you need an FMM (Forma Migratoria Múltiple). Usually, if your stay is under seven days and you're entering by land (which this bridge counts as), it's free, but if you're flying further into the interior like Mexico City, they might charge you the tourism fee which is roughly 700 pesos.
Keep that paper. Seriously. If you lose that little slip of paper, your trip home will involve a frantic visit to an immigration office and a fine that will ruin your mood.
Why Tijuana Beats LAX Every Single Time
Cost is the big one. If you look at Volaris, VivaAerobus, or Aeromexico, the prices for a flight to Mexico City from Tijuana are often half of what you’d pay from San Diego or Los Angeles. We’re talking $120 round trip if you book a few weeks out.
Then there’s the frequency. Tijuana's airport is a hub for the capital. There are flights leaving almost every hour. Missed your 10:00 AM? There’s probably an 11:15 AM.
The airport itself (General Abelardo L. Rodríguez International) has undergone massive renovations recently. It’s clean. The coffee is better than what you’ll find in Terminal 4 at LAX. And the VIP lounges are actually accessible if you have the right credit card or about 30 bucks.

Surviving the Flight and the Arrival
The flight is about three and a half hours. You’ll probably fly over the Baja peninsula, across the Sea of Cortez, and over the rugged mountains of mainland Mexico. It’s beautiful.
When you land at Benito Juárez International Airport (MEX), things get chaotic. It’s one of the busiest airports in Latin America. There are two terminals, T1 and T2, and they are not walking distance apart. If you’re on Aeromexico, you’re likely in T2. Volaris and Viva usually dump you in T1.
Don't take a random street taxi. Just don't. It’s not about safety as much as it is about getting ripped off. Use Uber or Didi. They work perfectly in Mexico City. However, there’s a catch: the airport regulations for rideshare apps change constantly. Sometimes you have to walk to a specific "Point" outside the terminal. Look for the crowd of people staring at their phones near a specific pillar; that’s usually the spot. If you want zero stress, go to a "Taxi Autorizado" booth inside the terminal, pay a flat rate, and take the ticket to the curb. It’s more expensive than Uber, but it’s guaranteed.
The Neighborhood Dilemma
Once you’ve made it to Mexico City from Tijuana, where are you staying?
- Roma Norte/Condesa: This is where everyone goes. It's leafy, European-style streets, incredible coffee, and dogs wearing sweaters. It’s safe, but it’s also "The Bubble."
- Juárez: A bit more "lived-in" than Roma but rapidly gentrifying. Great Korean food and very central.
- Centro Histórico: Intense. Loud. Historic. If you want to be steps away from the Zócalo and the ruins of Templo Mayor, stay here. Just know that the noise doesn't stop until 3:00 AM.
- Polanco: The Beverly Hills of Mexico City. If you want high-end malls and fancy dining (think Pujol or Quintonil), this is your spot.
What Most People Get Wrong About the Altitude
Mexico City is at 7,350 feet. That is significantly higher than Denver.
When you arrive from the coast, you will feel it. Your head might throb. You’ll get winded walking up a flight of stairs. You will get drunk on exactly one tequila.
Drink twice as much water as you think you need. Seriously. Hydration is the only way to beat altitude sickness. Also, the air quality can be rough in the winter months because the city sits in a volcanic basin that traps smog. If you have asthma, bring your inhaler.
Eating Your Way Through the Capital
You’re here for the food. We all are.
Street tacos are the lifeblood of the city. Look for the stands with the biggest crowd—locals don't stand in line for mediocre food. Tacos al Pastor is the king here. It’s pork marinated in dried chilies and spices, cooked on a vertical spit (trompo), and served with pineapple.
But don't sleep on the "Comida Corrida." These are small, family-run spots that serve a three-course lunch for about 100 to 150 pesos. You get a soup, a main dish (like milanesa or guisado), a dessert, and a flavored water (agua fresca). It’s the most authentic way to eat.
Real Talk: The Water
Don't drink the tap water. Not even for brushing your teeth if you have a sensitive stomach. Most Airbnbs and hotels provide "garrafones" (large jugs) of purified water. Use them.
Navigating the Mega-City
The Metro is efficient and incredibly cheap (5 pesos). It’s also a sensory overload and gets packed tight during rush hour. If you’re a woman, look for the women-only cars at the front of the train; they are strictly enforced and much more comfortable during busy times.
If you aren't feeling the subway, use the Metrobus. It runs in dedicated lanes down major avenues like Insurgentes and Reforma. It’s faster than an Uber during the 6:00 PM traffic apocalypse.
Speaking of traffic: Mexico City traffic is a sentient beast. A 5-mile trip can take 15 minutes or 90 minutes. Never trust Google Maps' initial estimate during peak hours. Add a 30-minute buffer to everything you do.
The Best Way to Spend Your Time
If you only have a few days, focus on the big hitters but leave room for wandering.
- The Anthropology Museum: It’s arguably one of the best museums in the world. You could spend three days here and not see it all. Focus on the Aztec and Mayan halls if you're short on time.
- Castillo de Chapultepec: The only real castle in North America that actually housed royalty. The views of Reforma from the balcony are staggering.
- Lucha Libre: Go to Arena México on a Tuesday or Friday night. Even if you hate wrestling, the energy is infectious. Buy a mask. Scream until you lose your voice.
- Xochimilco: Yes, it’s touristy. Yes, the water is murky. But sitting on a colorful boat (trajinera) with a bucket of beers and a mariachi band floating alongside you is a core Mexico City experience.
Safety and Common Sense
Is it safe? Generally, yes. The areas where tourists hang out are heavily policed.
Pickpockets are your biggest threat. Keep your phone in your front pocket. Don't flash a stack of cash at a market. Use common sense. If a street looks dark and empty, don't walk down it.
The biggest "danger" is actually the uneven sidewalks. You will trip. You will stumble over a loose brick. Wear comfortable shoes with grip. Leave the heels at home.
Actionable Steps for Your Trip
If you’re ready to pull the trigger on a trip to Mexico City from Tijuana, here is exactly how to execute it without the stress:
- Book the flight first: Use a search engine to find the dates, then go directly to the airline's website (Volaris or Aeromexico) to book. It’s easier to handle changes that way.
- Secure your CBX pass: Buy it online and save the QR code to your phone's digital wallet.
- Reserve your parking: The lots at CBX fill up fast. If you’re driving from San Diego, book a parking spot in advance or take an Uber to the terminal.
- Download the apps: Get Uber and Didi. Also, download an offline map of Mexico City on Google Maps.
- Notify your bank: Mexican ATMs can be finicky. Let your bank know you’re traveling so they don't freeze your card the first time you try to buy a taco.
- Check your passport: It needs to be valid for the duration of your stay. Mexico doesn't strictly require six months of validity like some countries, but it’s a good rule of thumb to avoid hassles.
Getting to Mexico City from Tijuana is a travel hack that saves hundreds of dollars and cuts out the bureaucracy of major U.S. hubs. It turns a massive international journey into a simple, domestic hop. Once you're sitting in a park in Condesa with a coffee in hand, you’ll realize the bridge was the best part of the plan.
